Eastin is listed as the line judge in Sunday's St. Louis Rams-Detroit Lions game, making her the first woman to be an official in a regular-season game.

She is among the replacement officials hired by the league while the regular officials are locked out. Replacement officials are working games for the first time in 11 years.

Eastin became the first female official to work an NFL preseason game last month as the line judge when Green Bay played at San Diego. The Pro Football Hall of Fame has the hat and whistle she used during that preseason game, and they'll be displayed in Canton, Ohio.
